Leases And Commitments [Abstract]
Leases And Commitments	9. Leases and Commitments We believe that our facilities are adequate and suitable for our current needs. We lease approximately 6,000 square feet of office space pursuant to a non-cancelable operating lease in Austin, TX that expires in December 2017. Future minimum lease payments are $0.1 million in 2017. Rent expense was $0.1 million in 2016, 2015 and 2014. We conduct our product research and development programs through a combination of internal and collaborative programs that include, among others, arrangements with universities, contract research organizations and clinical research sites. We have contractual arrangements with these organizations, however these contracts are cancelable on thirty days’ notice and our obligations under these contracts are largely based on services performed.
